Winsock Error 10091


WSAEADDRINUSE (10048) Address already in use. In this case, it might be possible to check the count of TCP RST packets received, or ICMP Port Unreachable packets. User suggestions: Did you enter a destination hostname? the HTTP, HTTPS, FTP diagnostic is also in the red.

The explanation is simple and obvious: in order to connect to or send to a destination address, you need to provide the destination address. Some of these neglected error values are among those mentioned earlier that provide "finer resolution" on different WinSock implementations. If an application sends a UDP packet to a host/port that does not have a datagram socket "listening," the network system may respond by sending back an ICMP Port Unreachable packet Windows Sockets only allows a single blocking operation—per- task or thread—to be outstanding, and if any other function call is made (whether or not it references that or any other socket)

This error occurs when the sin_port value is zero in a sockaddr_in structure for connect() or sendto().

A couple functions that the v1.1 specification missed are WSASetLastError() and WSAUnhookBlockingHook(). For inet_addr(), this could mean the content of the buffer passed or the buffer itself is invalid. Not sure how to do them all at once. Here is a useable macro: #define MAKEWORD(low, high) ((WORD)(((BYTE)(low)) | (((WORD)((BYTE)(high))) << 8))) WinSock functions: WSAStartup().

Try downloading and installing the Microsoft Winsock update from: This should hopefully fix your problem as well as update your Winsock files. The service provider procedure call table is invalid.
